Abstract:

Lipoleiomyoma is relatively rare, and even rarer to appear in the uterus and extrauterine at the same time. We report a case of multiple lipoleiomyoma of uterine and extrauterine. The patient was suggested the possibility of a teratoma of the right ovary, and recommended laparoscopic exploratoration. A right posterior uterine wall inter teratoma muscular exophytic nodule, a solid mass at the end of the appendix and a solid peritoneal mass in the posterior wall of the bladder were found during operation. Postoperative histological pathology and immunohistochemistry showed the lipoleiomyoma. Lipoleiomyoma is a rare benign tumor, mostly in the uterus. The occurrence of extrauterine lipoleiomyoma may be attributed to implantation after gynecological surgery. Clinical symptoms of uterine and extrauterine lipoleiomyoma are atypical. As the fat within the mass can be detected on imaging examination, especially when the mass is adjacent to the adnexal, it is more likely to be misdiagnosed as ovarian teratoma. MRI should be performed if necessary, to improve the detection rate. The treatment of uterine and extrauterine lipoleiomyoma is mainly surgical resection, with a good prognosis. There is a risk of malignant transformation or coexistence with other gynecological malignancies, so the long-term postoperative follow-up is required.
